Frequently Asked Questions
What is the time difference between KST and MSK?
During standard time, Moscow Standard Time is 6 hours behind Korea Standard Time.
Does South Korea observe Daylight Saving Time?
South Korea does not observe Daylight Saving Time and has not done so since 1988, when DST was discontinued following the Seoul Summer Olympics. KST remains fixed at UTC+9:00 every day of the year, meaning the offset between Seoul and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Are KST and JST the same?
Yes, Korea Standard Time (KST) and Japan Standard Time (JST) share the identical UTC+9:00 offset, and neither country observes Daylight Saving Time. Seoul and Tokyo run on exactly the same clock year-round, which directly supports the deep semiconductor, automotive, and consumer electronics supply chain integration between the two economies.
Does Russia observe Daylight Saving Time?
Russia abolished Daylight Saving Time entirely in 2014, settling permanently on standard time after a contentious experiment with year-round summer time that began in 2011. Moscow Standard Time has remained fixed at UTC+03:00 ever since, with no seasonal clock changes of any kind.
Are MSK and Eastern European Summer Time (EEST) the same?
During summer, countries observing Eastern European Time — including Ukraine, Romania, and Greece — shift to EEST at UTC+03:00, which numerically matches MSK exactly. However, MSK holds at UTC+03:00 year-round, while EEST is a temporary designation that reverts to UTC+02:00 when those countries return to standard time each autumn.
